[Laser] Lenses?

Kurt,

Burr-Brown sells the opt-301 integrated op amp and Photodiode assembly. 
They are slightly pricey, but you determine the bandwidth by putting in 
your own feedback resistor-so it's 'custom'.

They come with an onboard resistor too, which gives 4 to 6 khz bandwidth 
and come in a shielded package-so the shielding requirement is minimal. 
They sell for around 16 buks each.

--------

The opt-101 is even cheaper and easier to use (single supply) and has the 
same sensitivity as the 301. It comes in an unshielded package tho, but 
they only cost 6 dollars each.

-------

If anyone orders opt-101's, please let me know as I'd like to have 2 of 
them and I can't make the minimum order by myself.

------

Regards,

Art
